We create precision-engineered 3D printable designs tailored specifically to your project requirements. Whether you need a custom fabrication jig, welding fixture, workshop tool, or a unique automotive solution, every design is developed with functionality, durability, and ease of printing in mind. Combining practical fabrication experience with advanced CAD design, we deliver print-ready files built for real-world performance.
Customer feedback is essential to our process and helps drive continuous improvement across our product line. We appreciate your trust in us and look forward to supporting your next build.
Precision 3D Printed Jigs for Automotive Fabrication
Metal 3D Printable Designs & Components
We design high-performance components specifically for metal additive manufacturing, creating solutions that take full advantage of the capabilities offered by modern metal 3D printing processes. Whether you're looking for a digital file to manufacture yourself or a finished metal component, our designs are engineered with strength, functionality, and real-world performance in mind.
Our focus is on producing optimised, production-ready designs for automotive, fabrication, motorsport, and industrial applications. Every model is developed to suit its intended use, with careful consideration given to manufacturability, material performance, and practical application.
Customers can purchase either the digital design files for manufacture through their preferred metal 3D printing provider or order finished metal parts manufactured by our trusted production partners. This provides the flexibility to integrate our designs into your own workflow or receive a professionally produced component ready for use.
Whether it's a custom fabrication tool, workshop accessory, performance component, or a bespoke engineering solution, we deliver designs created specifically for metal additive manufacturing—not simply adapted from conventional manufacturing methods.
Shown below is a custom merge collector and T3 turbo flange engineered by RK Designs for SM Works. The components were manufactured in stainless steel via metal additive manufacturing from our design files and subsequently used in the fabrication of a bespoke exhaust manifold for the Nissan SR20 engine.
This project highlights the advantages of designing specifically for metal additive manufacturing, enabling complex geometries and high-performance components for demanding automotive applications.
About RK Designs
Welcome to your go-to source for high-quality 3D printed jigs and aids for automotive fabrication. Our passion for precision and innovation drives us to create top-notch products that elevate your fabrication experience. We aim to provide cutting-edge solutions that meet the diverse needs of automotive enthusiasts and professionals.
From the success of selling digital files on Cults I have now increased the availability to people without the use of a 3D printer, I will be bringing across all the files from Cults over to my website to purchase.
